In space no one can hear you scream… or much of anything for that matter. You can’t make noise in space. In order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules, and of course in deep space, there are no molecules in the empty void to vibrate in the first place.
The only way to communicate across space is to use satellites which transmit radio signals. It can be pretty creepy to think of how many little satellites we have circling the Earth, floating in the vacuum, sending messages into the abyss. Makes you wonder if anything has ever tried to send a message back to us?
And now, after almost half a century of silence, a satellite has started transmitting eerie signals spontaneously. The LES 1 satellite, or the Lincoln Experimental Satellite series, was designed and built by Lincoln Laboratory at MIT under USAF sponsorship, for testing devices and techniques for satellite communication. The satellite was launched in 1965, but was lost in 1967. Amateur astronomers first suspected they’d found the LES1 satellite in 2013, but needed three years to confirm it had really started working again.
Now they’ve managed to decode the signals being beamed back from the mysterious satellite, and can hear ghostly noises issuing from it. Phil Williams from North Cornwall, in the United Kingdom, had detected signals from LES1 and determined the source after searching for identifying information on the internet.
LES1 was determined to be tumbling at about a 4-second interval (rotation speed), as determined by the distinctive fading of the signals. It has been suggested that, after 46 years, the batteries have failed in a manner that allows them to carry charge directly through to the transmitter on 237 MHz, allowing it to start up when it is in sunlight.
There’s been a heck of a lot of UFO activity over the last year, and while this doesn’t explicitly confirm or deny the existence of intelligent alien life, it just goes to show that the search must go on. We could very well be communicating with extraterrestrials in the near future. After all, Stephen Hawking has just backed a $100 million pledge to find alien life.
